Oregon gas tax and minimum wage going up?

Sad that people don't realize that you cannot raise the minimum wage in a vacuum. If minimum wage rate is increased to $15.00 an hour, all those people making more than minimum wage now are going to want comparable increases. Someone currently making $15.00 (approx. double the current minimum) they are going to want raises to $30.00 which would be double the new rate. I mean, why have a skill or education if it doesn't make you more money than a burger flipper. Everything will rise in price. Not just your Big Mac. In the end, the buying power of the minimum wage worker will remain about the same. They can buy two $3.75 Happy meals an hour today, they will be able to buy two $7.50 happy meals 6 months after their wages go up. The cities that have drastically raised minimum wage today can do it with little bad effects because it hasn't had the ripple effects out to their suppliers who operate outside the high wage zone since the farmer, truckers, bun makers, pickle picklers and the like are still paying $7.50 to their employees in the suburbs. Make it statewide or nationwide and prices and wages will rise until they reach an equilibrium which will leave everyone with basically the same buying power as today. $15.00 an hour wages will be offset by $15.00 burgers.
